A Nichrome wire 75 cm long and 0.35 mm in diameter is connected to a 1.4 volt flashlight battery. What is the electric field inside the wire?The answer is in voltmeter , but the volume is m^3, so you can't just divide by the voles by the volume. Do I use the radius or the length? I think length because radius is m^2, but can anyone verify for me?
